Popped into the 99p store yesterday, saw they had a decent collection of kids DVD's. Best of the lot was a bunch of Superted DVD's, they had:
SuperTed - The Original Adventures Of SuperTed
Superted - Superted In The Arctic
Superted - Trouble In Space
SuperTed Kicks Up The Dust
Checked Find- DVD and cheapest I can find each of these online is about £4, you can get the whole collection for that much. Each contained at least 6 episodes and none of them duplicated.
